Prime Power vs. Base-Load Operation and Relevance to Data Centers
Prime power and base‑load power are frequently used interchangeably, but they describe different operating conditions for gas engines. Understanding these distinctions is critical for data‑center power design, resilience planning, and long‑duration bridging power.
LHV vs HHV in Data Centers: Why Fuel Definitions Matter for Onsite Power Economics
LHV and HHV are often confused in data‑center energy modelling. Because gas‑engine performance is measured using LHV while fuel is billed using HHV, mixing the two can distort efficiency, fuel forecasts, and long‑term cost planning.
Why Gas Engines Behave Differently Under Partial Load – and Why Data Centers Should Care
Modern data centers rarely operate at full load, making partial‑load engine behavior critical. Gas engines offer high efficiency, fast ramp rates, and strong integration with UPS and BESS systems—helping operators improve resilience, performance, and long‑term economics.
